8 Claims.

Our invention relates generally to means for cushioning the slamming ofa door, and particularly to means of this character which is mounted onthe door and occupies a position between that part of the door whichordinarily strikes the jamb in closing, and the jamb itself, in the formof a compressible or shock absorbing pad, and an important object of ourinvention is to provide simple and effective means of this characterwhich can be constructed in various inexpensive forms. Another importantobject of our invention is to provide bumper means of the characterindicated which is adapted to be mounted on one of the door handles andfrictionally engaged therewith ina manner to rotate with the door handleso as to be positioned by the door handle normally in the shockabsorbing position.

Another important object of our invention is to provide bumper means ofthe character indicated above which has a carrying portion securelyfastened to the door handle by means of structure already present on theconventional door handle, and whereby the bumper means is positivelypositioned by reason of the position of the 1' door handle.

Other important objects of our invention will be apparent from a readingof the following description taken in connection with the drawings,wherein for purposes of illustration we have shown preferred embodimentsof our invention.

In the drawings:-- Figure 1 is a general elevational view of the innerside of-a door showing an embodiment of the invention mounted on thedoor handle there- Figure 2 is an enlarged top plan view and horizontalsection showing the relationship of the door, the bumper and the doorjamb, and the manner in which the bumper is mounted on the door handle.

Figure 3 is an end or edge elevational view of Figure 1.

Figure 4 is a side elevational view of the bumper per se.

Figure 5 is an end elevational view of Figure 4.

Figure 6 is a view similar to Figure 2 but showing'a modified form ofbumper.

Figure 7 is a longitudinal vertical sectional view taken through Figure6 approximately on the line 'l---'! and looking upwardly in thedirection of the arrows.

Referringin detail to the drawings, and with particular reference to theembodiment of the invention shown in Figures 1 through 4, the numeral I'generally designates the bumper which in .which is inserted in andfastened at one this instance is made of suitable compressible andresilient material, such as rubber and comprises an elongated shank onone end of which is an integrally formed eye 2 which has the opening 6which frictionally receives the shank portion 3 of the door handle 4closely adjacent to the inner surface of the door 5. The remaining endof the shank of the bumper has a cross head 1 integrally formed thereonwhich is adapted to assume, normally, a position between the inner sideof the free edge of the door 5 and the opposed face of the door jamb 8on the door frame 9 as particularly well illustrated in Figure 2 of thedrawings. The opening 6 in the eye of the bumper is small enough toproduce a strong frictional fit on the shank of the door handle, so thatit will be substantially securely mounted thereon and will turn with thedoor handle when the door handle is turned. The bumper is so positionedon the shank of the door handle that when the door handle is in thenormal unoperated position the head 1 will lie in the position shown infull lines in Figure 1 and Figure 2 of the drawings, so that should thedoor he slammed from an open position, the head 1 of the bumper willabsorb the shockand prevent injury to the door and the door jamb as wellas reduce the noise ordinarily occurring in the slamming of a door.

Referlng now to the embodiment of the invention shown in Figures 6 and7, the numeral ID generally designates the embodiment which in thisinstance comprises a flat metal spring arm ll end in a resilientcompressible material head 7a and has its opposite end 'bent into a coilI2 and of a diameter permitting the telescoping of the shank portion 3aof the door handle 4a thereinto. The

free end of the coil I2 is provided with an opening l3 to receive theset screw M which is normally existent on the door handle for engagingthe squared shank l5 of the door handle axle whereby the door handle issecured in place on the axle. The screw I4 is passed through the openingI3 and threaded into the shank 3a, so that the member l I extendsexactly in the position required to place the cross head !a in the shockabsorbing position relative to the jamb 8d of the door frame 9a and theinner face of the door Set as illustrated in Figures 6 and 7, while thedoor handle 4a is in its normal or initial position. When the doorhandle 4a is rotated in looking the door to close the same, the bumperwill be carried by the motion of the door handle to an inoperativeposition such as those indicated in dotted lines in Figure 1 of thedrawings.

Although we have shown and described herein preferred embodiments of ourinvention, it is to be definitely understood that We do not desire tolimit the application of the invention thereto, and any change orchanges may be made in the materials and in the structure andarrangement of the parts, within the spirit of the invention and thescope of the subjoined claims.

What is claimed as new is:- V
